BITREX®

QUALITATIVE FIT TEST INSTRUCTIONS

A. EQUIPMENT REQUIRED
1. Moldex Bitrex Qualitative Fit Test Kit (#0102)
2. Moldex Bitrex Quantative Test Hood (#0201)
3. Nebulizer #1 (BITREX Sensitivity Solution) (#0301)
4. Nebulizer #2 (BITREX Fit Test Solution) (#0302)
5. Two sets Replacement Nebulizer Inserts
6. BITREX Fit Test Solution Applicator Tube (#0504)
7. BITREX Sensitivity Solution Applicator Tube (#0503)
8. Appropriate Moldex Respirators*

8. Once the applicator solution has been drained into the nebulizer, it cansafely be disposed.
9. Ensure that each nebulizer is able to produce solution mist via the exhaust
port by removing plug from Breather Vent and squeeze bulb 4-5 times. Ifsolution mist is not visible or seems very weak, carefully (so not to spill thesolution) remove the top half of the nebulizer by unthreading it from thebottom half and repeat #B-2. (See Diagram 1). (Repeat for each nebulizer)*Use with any Moldex N, R or P class disposable respirator. This fit test kit may also
be used with any Moldex half mask or full face respirator by using any N, R or P class filter.
**This fit test kit may also be used with any Moldex half mask or full face respirator by using any
N, R or P class filter as a stand alone or in combination with any chemical cartridge. The maximum
fit-factor allowed for qualatatively fit testing a Full Face is 10.

B. NEBULIZER PRE-INSPECTION AND
PREPARATION
1. Remove the top half of the nebulizer
by unthreading it from the bottom
half. (Repeat for each nebulizer)
2. Using your index finger lightly pushdown on the Atomizer to ensure that it
is pushed down all the way onto thebottom half of the nebulizer. (SeeDiagram 1). (Repeat for each nebulizer)
1
3. Inspect and ensure that the black
O-ring is properly seated.
(Repeat for each nebulizer)
4. Replace the top half of nebulizer and remove plug from nebulizer exhaust
port. (Repeat for each nebulizer)
C. BITREX APPLICATOR INSTRUCTIONS
5. WARNING: When crushing the applicator tubes to release the product,
it is important to wear protective gloves. It is also important to “pinch”the applicator tube to break the glass ampoule when releasing the liquid
into the tube. DO NOT BEND THE TUBE! (See Diagrams 2 and 3)
6. PREPARATION: Remove Sensitivity Test Applicator and/or the Fit Test
Applicator from its storage box. With the fill tip pointed upward, pinch
along the full length of the applicator tube using your thumb and forefinger
until glass ampoule inside of the applicator tube is thoroughly crushed.
(Warning: It is important to keep the applicator tip pointed upward whenpinching the tube. This is to prevent the solution from squirting out duringthe pinching process.) (See Diagram 4)
7. Remove the End Cap from the nebulizer. Insert the applicator tip into theopening of the nebulizer. Squeeze along the applicator tube to transfer thesolution from the applicator down into the nebulizer until the applicator iscompletely drained of the solution. (Warning: Do not attempt to remove
the tip of the applicator. It contains a porous filter which is designed toallow the solution to pass through it while filtering out the glass ampouleparticles. It is also not necessary to puncture a hole or cut the tip of theapplicator. The applicator tip already has the proper hole size in it to allow
the solution to squirt into the nebulizer.) (See Diagrams 5 and 6)(Note: It is recommended that the protective end cap be replaced back on
the nebulizer until the test is ready to be performed.) Use the foamcushion insert in the fit test kit to hold the nebulizer(s) upright.

2D. TASTE SENSITIVITY SCREENING
Purpose: This test is done to ensure that the person being fit tested candetect the taste of BITREX at sufficiently low levels to make the fit test valid.
1. Ensure that the test subject does not eat, drink, smoke or chew gum for
15 minutes before the test.
2. Explain the screening and fit testing procedures to the subject.
3. Instruct subject to put on the hood without a respirator.
4. Position the hood forward so there is about six inches between thesubject’s face and the window. This is especially important for the fit test.
It allows free movement of the head when the subject is wearing arespirator and helps ensure even dispersion of the aerosol around theface seal area.
5. Instruct the test subject to breathe with their mouth slightly open andtongue extended.
6. Using the nebulizer labeled BITREX Sensitivity Solution, inject the aerosol
into the hood through the hole in front of the enclosure. Inject ten (10)squeezes of the bulb, fully collapsing and fully expanding the bulb oneach squeeze.
7. Ask the subject if he can detect the bitter taste of BITREX.
8. If the subject does not detect bitter taste, inject an additional ten
squeezes into the hood.
9. If the subject still does not detect bitter taste, inject an additional tensqueezes, for a total of 30 squeezes.
10. If 30 squeezes were inadequate to elicit a response from the subject,
this subject cannot be fit tested with the BITREX test. Another fit test
method must be used.
11. If the subject could detect bitter taste, the number of squeezes required
to produce a taste response should be noted, i.e., 10, 20 or 30squeezes, even if subject tasted the BITREX on a number of squeezes
other than multiples of ten.
12. Remove the hood. Wait a few minutes, to give the subject time to clear
the taste from his mouth, before proceeding to the fit test. A drink ofwater during this time will aid in removing the bitter taste. Use a paper
towel to wipe the subject’s mouth of any residue (also wipe mustaches).

QUALITATIVE FIT TEST INSTRUCTIONSCLEANING
Immediately after completing the test, discard any unused solutions. Rinsethe nebulizers with warm water to prevent clogging. Wipe inside of the hoodwith a damp cloth or paper towel to remove any deposited Test Solution.
RAINBOW PASSAGE
When the sunlight strikes raindrops in the air, they act like a prism and forma rainbow. The rainbow is a division of white light into many beautiful colors.
These take the shape of a long round arch, with its path high above, and its
two ends apparently beyond the horizon. There is, according to legend, aboiling pot of gold at one end. People look, but no one ever finds it. When aman looks for something beyond our reach, his friends say he is looking forthe pot of gold at the end of the rainbow.

OSHA
This fit test meets the performance criteria for fit testing respirators undercurrent OSHA Standards.

ISE. FIT TEST
1. Use any Moldex disposable N, R or P series class disposable respirator
or any Moldex half mask or full face respirator with any N, R or P seriesfilter. Have the test subject put on and adjust the respirator per theinstructions provided with the respirator. Have the subject select the size
respirator that provides the best fit. The subject may find a mirror usefulin the adjustment process. The subject should wear the respirator atleast five (5) minutes before starting the test.
2. Instruct the subject to put on and position the hood as before andbreathe with their mouth slightly open and tongue extended.
3. Using the nebulizer labeled BITREX Fit Test Solution, inject the fit test
aerosol into the hood. The same number of squeezes is required as wasnecessary to elicit a response in the threshold sensitivity screening test,i.e., 10, 20 or 30 squeezes.
4. To maintain an adequate concentration of aerosol during the test, one
half of the initial number of squeezes should be injected again every 30
seconds (i.e., 5, 10, or 15) through out the test.
5. After injecting the aerosol initially, ask the test subject to perform thefollowing exercises for 60 seconds each:(a) Normal breathing.
(b) Deep breathing.
(c) Turning head from side to side, stopping at each end of travel for one
or two breaths.
(d) Moving head up and down, stopping at each end of travel for one or
two breaths.
(e) Talking, reciting the alphabet, or reading a prepared text (the Rainbow
Passage is recommended, see below).
(f) Jogging in place.
(g) Normal breathing.
6. Instruct the subject to indicate if they detect the bitter taste at any time
during the test.
7. If the entire test is completed without the subject detecting the bitter
taste of the aerosol, the test is passed and the respirator’s fit on thatindividual is judged adequate.
8. At any time during the test, if the subject detects the bitter taste of theaerosol the test is stopped at this point. When this occurs, the fit of therespirator on the subject is judged inadequate.
9. If the test is failed, before retesting the subject, a 15-minute waiting
period must be observed and the taste sensitivity screening test must beperformed again. Test again with same Moldex model.
10. If the second test fails, repeat tests with another size and/or model
Moldex respirator.
11. Document results of fit tests for each employee.
